they cant just toss away literal video data, thats whats actually being requested to be played

2018-10-02 20:25:37 UTC  

they proccess video data

2018-10-02 20:25:39 UTC  

and images

2018-10-02 20:25:41 UTC  

For example, QR codes just encode images. You could write a plugin that transforms each image on the fly and renders the "hidden" video.

2018-10-02 20:25:42 UTC  

upon upload

2018-10-02 20:25:59 UTC  

In computer security this is very similar to what is known as a "side channel".

2018-10-02 20:26:45 UTC  

@Deleted User Yes, I know. But, it could be in the video frame itself. For example, QR codes encode URLs. You can create an arbitrary encoding for data that you then display in each frame.

2018-10-02 20:27:02 UTC  

Even just morse code. They then represent bits.

2018-10-02 20:27:15 UTC  

It might not be very compact, but creating such a "coded" video is doable.

2018-10-02 20:27:29 UTC  

You could even go so far that it only makes sense if the watchers have a particular private key.

2018-10-02 20:27:55 UTC  

It would look like static, unless you have the decryption key. It's not so different from the encoding that TV channels used.

2018-10-02 20:28:46 UTC  

Anyway. It's pretty wacky, but I am just going along with the thought experiment.

2018-10-02 20:28:59 UTC  

yea but all that encoded data

2018-10-02 20:29:03 UTC  

is going to be stored in a server

2018-10-02 20:29:08 UTC  

probably FOR EVER

2018-10-02 20:29:11 UTC  

Side channel?

2018-10-02 20:29:21 UTC  

matter of time till ai catches on into this shit

2018-10-02 20:29:24 UTC  

What you want to know?

2018-10-02 20:29:47 UTC  

Yes. Somebody brought up uploading an encoded video to YouTube that can be played, but is not viewable in its original form until decoded.

2018-10-02 20:29:49 UTC  

the best is just dont send em any info to them

2018-10-02 20:30:01 UTC  

I was just walking through how one could create such an encoded video.

2018-10-02 20:30:14 UTC  

@Undead Mockingbird what the fick does that mean?

2018-10-02 20:30:23 UTC  

theres this war against hardware in silicon valley

2018-10-02 20:30:37 UTC  

I was mentioning side channels, because in computer security, there have been amazing bugs that kind of inferred data through very unlikely means, such as the pattern of memory access by another process.

2018-10-02 20:30:37 UTC  

is like there a red tape on hardware

2018-10-02 20:30:47 UTC  

and only big ones are allowed to have hardware

2018-10-02 20:30:48 UTC  

Side channel attack would be taking a camera phone and record it while it is playing

2018-10-02 20:30:53 UTC  

So in confused

2018-10-02 20:31:02 UTC  

lol

2018-10-02 20:31:12 UTC  

Huh? No, I just explained what a side channel attack is in the context of computer security.

2018-10-02 20:31:42 UTC  

I do not know what term you are talking about, but if you are correct, there might be different uses of the term in different contexts.

2018-10-02 20:32:16 UTC  

This is what I am talking about: https://www.wikiwand.com/en/Side-channel_attack

2018-10-02 20:33:26 UTC  

Just like binary is just an arbitrary encoding, you can also encode arbitrary data in movies.

2018-10-02 20:34:03 UTC  

Just like any of the letters of this sentence can be represented in numbers, such as their unicode encoding.

2018-10-02 20:34:14 UTC  

But the issue is you want to decrypt it in a mitm attack?

2018-10-02 20:34:26 UTC  

Why not just record it on the player level

2018-10-02 20:34:31 UTC  

I don't know if that was the intention.

2018-10-02 20:34:59 UTC  

I was using the example of the side channel attacks as an example of how regular communication and processes can be piggy backed on to communicate other information.

2018-10-02 20:35:08 UTC  

Not really
